Many individuals who use vaping products report experiencing nausea or vomiting. This article explores the various factors that can contribute to these uncomfortable sensations.
Nicotine’s Impact on the Body
Nicotine, a primary component in most vape liquids, acts as a stimulant that affects the central nervous system. When inhaled, nicotine rapidly enters the bloodstream and interacts with receptors in the digestive tract. This interaction can alter gut motility, potentially leading to increased stomach acid production and nausea.
Rapid or excessive nicotine intake can quickly overwhelm the body, leading to “nicotine sickness” or acute nicotine toxicity. Symptoms often include dizziness, headaches, cold sweats, tremors, abdominal discomfort, and nausea. The severity directly correlates with the amount of nicotine absorbed.
Vape liquids vary widely in nicotine concentration, with some, like nicotine salts, allowing faster absorption. Higher wattage or voltage devices also accelerate nicotine delivery. Consuming nicotine too quickly can overload the liver’s detoxification process, causing nicotine to accumulate and trigger the body’s protective response, including nausea and vomiting. High nicotine content and efficient delivery can quickly push the body past its tolerance threshold.
Other Vape Liquid Ingredients
Beyond nicotine, other components in vape liquids can contribute to digestive issues. Propylene Glycol (PG) and Vegetable Glycerin (VG) are base liquids, producing vapor and carrying flavor and nicotine. While generally safe, some individuals may have sensitivities to PG, manifesting as gastrointestinal discomfort like bloating, gas, or nausea.
Both PG and VG are hygroscopic, attracting and absorbing water. This can contribute to dehydration as vaping pulls moisture from the mouth and respiratory tract. Dehydration is a common cause of nausea and can exacerbate digestive upset. Maintaining adequate hydration is important for vapers.
Flavorings, though often food-grade, can behave differently when heated and inhaled compared to ingestion. Certain artificial flavorings, such as cinnamaldehyde or diacetyl, have been linked to irritation when inhaled. This irritation can extend to the respiratory system and, upon systemic absorption, affect the digestive tract, triggering nausea. Poorly manufactured e-liquids or contaminants can also introduce harmful substances, leading to digestive distress.
Vaping Practices and Their Effects
Specific vaping habits can influence the likelihood of nausea. “Chain vaping,” continuous and frequent device use, leads to rapid accumulation of nicotine and other chemicals. This constant exposure can overwhelm the body’s systems, making acute nicotine toxicity and nausea more probable.
Improper device settings can also contribute to discomfort. High wattage or voltage can overheat e-liquid, resulting in “dry hits” or a burnt coil taste. This produces harsh, irritating vapors containing breakdown products like formaldehyde or acrolein. Inhaling these compounds can irritate the throat and lungs, potentially triggering a gag reflex or causing nausea.
Vaping can contribute to dehydration, as PG and VG draw moisture from the user’s mouth and airways. Increased exhalation of water vapor also plays a role in fluid loss. Dehydration is a known cause of nausea, headaches, and fatigue, and can worsen existing feelings of sickness. Inadequate fluid intake while vaping can exacerbate gastrointestinal discomfort.
Improper inhalation techniques can lead to adverse effects. Drawing too hard or quickly on a vaping device may cause individuals to swallow excess air, resulting in bloating and abdominal discomfort. Inhaling excessively harsh vapor due to poor technique can induce coughing fits and malaise, potentially contributing to nausea.
When to Seek Medical Advice
While occasional nausea from vaping might resolve, certain symptoms warrant immediate medical consultation. Seek professional help for severe or persistent vomiting lasting over 24-48 hours. Other warning signs include vomiting blood, severe abdominal pain, chest pain, or difficulty breathing.
Severe dizziness, confusion, or fever with nausea and vomiting after vaping also indicate a need for medical attention. These symptoms could signify a serious underlying health issue or severe nicotine toxicity. Be honest with healthcare providers about vaping habits for accurate diagnosis and treatment.
